Answer 1

volume of hemisphere at bottom = 2/3(πr^3)
= 2/3(π•3.5^3)

= 89.79 cm^3

volume of cylinder = πr^2h = π•3.5^2•14

= 538.78 cm^3

hence volume of mog used by owner B = 538.78- 89.79 = 449 cm^3 = 0.449 litre

since 1 litre price is = RS 80
hence

0.448 litre = Rs 80×0.45 = Rs 36

hence price of one mug of milk by owner B = Rs 36


the value exhibited by owner B = price by owner A - Price by owner B
= 43.12 - 36
= Rs 7.12
